MapleSim Tire Component Library

Maplesoft has announced a new add-on for its physical modelling and simulation product MapleSim. The MapleSim Tire Component Library lets engineers extend their multi-domain MapleSim vehicle models with high-performance pneumatic tire components.

The MapleSim Tire Component Library provides MapleSim users with industry-standard tire force model components. In addition, linear and user-defined tire models are available to provide flexibility for investigation and analysis. With the easy-to-use point-and-click MapleSim graphical environment, these fully parameterised force models can be integrated into existing vehicle dynamics models by simply dragging the component into a diagram and connecting the component to the vehicle model.

In the library, kinematic quantities, such as slip angle, longitudinal slip, and inclination angle are derived automatically and available to the user. These quantities are used to determine the tire forces and moments.

Engineers can control how the tire slip and rolling radius are calculated, and include tire transients through differential equations involving relaxation lengths.

Support for the following industry-standard tire models is also included: Fiala, Calspan, and Pacejka 2002. For custom research and development applications, user-defined tire models can be constructed easily using an intuitive interface.

Since the MapleSim Tire Component Library is a fully integrated add-on package to MapleSim, the tire model components can take full advantage of features available to MapleSim components.
